ChatGPT SEO makes your site a clear, reachable source for ChatGPT search. People now ask ChatGPT for advice, products, and local services. The aim is to help those customers find you when it cites sources.
OpenAI doesn't publish a ranking formula. It does document how search works and what makes a site eligible. This guide sticks to that documentation and turns it into a checklist.
Reporting note: We checked this guide against OpenAI's documentation on October 14, 2026.
Key takeaways
- OpenAI says placement in ChatGPT search isn't guaranteed
- Allowing OAI-SearchBot makes your site eligible for ChatGPT search answers
- Blocking GPTBot for training doesn't change your search setting
- Pages that answer one question at a time are easier to cite
- Matching business details on every listing give AI tools one clear story
How does ChatGPT search the web?
ChatGPT can search the web when a question needs current information. A person can also start a search from the tools menu. Answers that use search may include citations and a Sources panel.
OpenAI says ChatGPT sometimes partners with other search providers. It rewrites a person's question into one or more targeted queries. It may then run more specific searches after it reviews the first results.
That matters for you. One customer question can turn into several searches. Pages that answer the narrow follow-up questions may get more chances to appear.
Our guide to query fan-out covers the same idea in Google's AI Mode. The lesson carries over. Cover the questions around your main service, not just the main term.
Can ChatGPT reach your website?
OpenAI runs separate crawlers for separate jobs. Only one of them decides whether you can appear in search answers. Here's how they split, based on OpenAI's crawler documentation.
Scroll sideways to read the full table.
| Crawler | What it does | What blocking it means |
|---|---|---|
| OAI-SearchBot | Finds pages for ChatGPT search | Your pages won't show in search answers |
| GPTBot | Collects content that may train models | Your content shouldn't train future models |
| ChatGPT-User | Visits a page when a person asks | Robots.txt rules may not apply |
The settings work on their own. You can allow OAI-SearchBot and still block GPTBot. OpenAI says robots.txt changes can take about 24 hours to take effect.
A site that blocks OAI-SearchBot can still show up as a plain link. It won't appear inside ChatGPT's search answers, though. For most businesses that want customers to find them, that's a poor trade.
Check your robots.txt and firewall first
Start with the technical door. If ChatGPT's search crawler can't get in, nothing else on this list matters. These checks take minutes.
- Open your robots.txt file in a browser
- Look for any rule that names OAI-SearchBot
- Check for a blanket rule that blocks every crawler
- Ask your host whether its firewall blocks AI crawlers
- Allow OpenAI's published search crawler addresses if it does
OpenAI's help page names that last step directly. It asks owners to confirm their host or content delivery network allows its crawler. Security settings can stop bots without anyone noticing, so ask.
What kind of page is easy for ChatGPT to cite?
OpenAI says ChatGPT ranks results on several factors meant to surface relevant, reliable information. It also says it doesn't guarantee placement. So the safe bet is the same work that helps people.
Google's advice on helpful content is a good model here. It asks whether a page offers original, useful information written for people first. A page that passes that test gives any search tool something worth quoting.
- One clear question per page or section
- A direct answer in the first two sentences
- Specific details like service areas, hours, and turnaround times
- Headings that match how customers phrase questions
- Key facts in page text, not only inside images or PDFs
- A visible date when you update facts
For example, a plumber might build a page around one question. Say it's "Do you fix tankless water heaters in Tampa?" A short, plain answer near the top is easy to quote.
Make your business easy to describe
ChatGPT draws on many sources to describe a business. Mixed details across those sources can lead to a muddled answer. Consistency is a simple fix you control.
Local searches add another layer. OpenAI says ChatGPT may use your general location to find nearby results. It may share that location with providers of local business listings.
So your listings matter, not just your website. Restaurant results, for instance, can show booking times from OpenTable, Resy, or Yelp. Check these details on your site and every listing:
- Your business name, written the same way everywhere
- Services and service areas that match on each listing
- Hours that match your Google Business Profile
- An about page that says who you serve and where
- Reviews earned honestly, never bought
Mentions in local news and trade sites also shape how the web describes you. Our Digital PR work aims to earn that coverage so more customers find you.
What should you skip?
Some tactics claim to be shortcuts into AI answers. Most of them waste money or break rules. Leave these off your list:
- Fake reviews or planted forum posts about your business
- Hidden text written to steer AI tools
- Pages stuffed with keywords instead of answers
- Anyone selling a sure spot in ChatGPT answers
Fake reviews carry legal risk too. The FTC finalized a rule in 2024 that bans fake reviews and testimonials. It names AI-generated fake reviews directly.
How can you tell if ChatGPT sends you visitors?
Look for chatgpt.com in your analytics referral sources. If people click through from its answers, that's one place their visits can show up. Watch the trend over a few months, not a single week.
You can also ask ChatGPT about your own business. Use the questions your customers ask, with search turned on. Note which pages it cites and what it gets wrong.
Answers change from one session to the next. Treat each check as a snapshot, not a score. Our AEO audit guide covers a fuller check of where AI tools send customers.
